New bulbs for the t5 setup

[slough shark]

So, I've been at this for a year now and notice a lot of brown algae beginning to form. 120 gal footprint with an 8 bulb t5 unit over it.
I'm ordering new bulbs right away to combat the algae (and its been a year)and these are the bulbs I'm getting:

4 - G-mann Powerchrome t5 flourescent bulbs - Actinic plus
4 - URI 54W Aquasun t5 Flourescent bulbs (10,000K)


Any comments or something I'm missing?

best,
derek
